Verdict
AMD Instinct MI210
7.3 / 10 Expert Rating
A practical, PCIe-slot-friendly way to get CDNA 2 compute into a standard server, useful for smaller HPC and AI deployments, but clearly the entry point of its generation next to the dual-die MI250X and now well behind the MI300 series.
AMD Radeon RX 6600M
6.5 / 10 Expert Rating
A competent 1080p mainstream mobile GPU for its era, but RTX 3060 Laptop GPU laptops usually offer better upscaling and ray tracing for similar money.
